In 2010, the population of a city was 220,000. From 2010 to 2015, the population grew by 6.2%. From 2015 to 2020, it fell by 4.5%. How much did the population grow from 2010 to 2015, to the nearest 100 people?

The mean of the sample is 10 and median is 10.5

The mean of the sample is given by: (∑ tour day)/ n

where n is number of visitors  

∑ tour day =12 + 7 +9 + 10 + 11 +11

=> 60

so ∑ tour day = 60

n = 6

so mean = 60 /6

=> 10

so the mean of the sample is 10.

The median of the list is found by sorting the element in ascending order and then find the average of middle most value

so after sorting the list in ascending order we get:

7 , 9, 10 , 11 , 11 , 12

so the median = (10 +11 )/2

=> 10.5

Yes, the number, 4225, is a perfect square because it can be expressed as square of 65 which is a whole number, i.e., 4225 = 65².

In mathematics, a square number or perfect square is an integer that is the product of some integer with itself. For example, 25 is a square number, it is equals to 5² and can be written as 5×5. A perfect square always represented as second power of a number. Perfect Square Formula : Let us consider if N is a perfect square of a whole number x, then it can be written as N = product of x and x = x². So, the perfect square formula is, N = x². We have a number 4225. Now, we resolve 4225 into prime factors, we get, 4225 = 5×5×13×13 = 5×13×5×13

= 65×65 = (65)²

Hence, the square of 65 results 4225. Therefore, 4225 is a perfect square.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. The statement is not an equation if there is no "equal to" sign in it.

One of the significant forms used to express a straight line algebraically is the two point form. Each point on the line fulfills the equation for the line, which means that the equation for the line represents every single point on the line. When two points on a line, (x 1, y 1) and (x 2, y 2), are known, the two-point form of a line is used to get the equation of the line.

The scale used for measuring the intensity of the earthquake is Richter Scale.

American seismologists Charles F. Richter and Beno Gutenberg developed the Richter scale (ML), a numerical indicator of an earthquake's size, in 1935. The height of the greatest seismic wave, as measured by the logarithm of its amplitude (height), is used to calculate the earthquake's magnitude.

Although the original Richter scale has been supplanted by other, more precise scales in modern science, the Richter scale is still frequently used incorrectly in news reporting of earthquake severity as a catch-all name for the logarithmic scale that earthquakes are measured on.

In order to prove that ∠MPQ is congruent to ∠MLN, she requires that PQ and LN should be parallel.

What are parallel lines?

When two lines in a plane do not cross at any point, they are said to be parallel. Lines that never cross paths with one another and do not have a common junction point are said to be parallel. They are equally spaced apart and have the same incline.

We know that corresponding angles of parallel lines are equal.

As shown in the figure, ∠MPQ and ∠MLN are corresponding angles.

So, if she is provided that PQ and LN are parallel, then, she can prove that ∠MPQ is congruent to ∠MLN and thus, the triangles are similar.

Hence, she requires that PQ and LN should be parallel.

The inverse of f(x) = log₁₀(x) is 10ˣ.

A logarithm is an exponent to which a base must be raised to generate a given number. Expressed mathematically, x is the logarithm of n to the base a if ax = n, in which case one writes x = logₐn.

A logarithm is defined using an exponent.

aˣ = b ⇔ logₐb = x

Here, "log" stands for logarithm. The arrow's right part is read as "Logarithm of b to the base a is equal to x".

We have the function,

f(x) = log₁₀(x)

The subtraction is not commutative because the order in which we subtract numbers affects the result.

Commutative property is applicable only for addition and multiplication processes. Thus, it means we can change the position or swap the numbers when adding or multiplying any two numbers.

The commutative property of subtraction does not apply to all real numbers. Subtraction is not commutative because the order in which we subtract numbers affects the result. For example, if we subtract 3 from 5, we get 2. But if we subtract 5 from 3, we get -2. The commutative property only applies to addition because a + b = b + a for all real numbers.

No, Since earthquake waves lose energy as they move through the earth, shaking is less powerful away from the fault. Compared to high-frequency waves, low-frequency waves lose strength across distance more slowly.

The magnitude scale, which measures an earthquake's size, is unaffected by distance from the event. The extent of damage depends on how violently the ground shakes when an earthquake occurs.

The depth of the earthquake, the distance from the fault, the underlying soil, and the characteristics of the buildings, particularly their height, intensity, are the subsequent primary elements impacting earthquake shaking strength. The brightness of a celestial object, like a star or galaxy, as judged by an observer at a particular distance from the object is known as its apparent magnitude. The apparent brightness increases with decreasing distance between observer and object.

Step-by-step explanation:

I don't know how else this could be answered with the information given,

The distance between pylon B and pylon C is 1017.60 m, using the Pythagorean theorem.

The Pythagorean Theorem, also known as Pythagoras' Theorem, states that the area of the large square is equal to the sum of the areas of the two smaller squares.

In terms of algebra, the triangle's a and b are its legs, and its hypotenuse is equal to its product, a2 + b2 = c2.

Since it provides the foundation for the definition of distance between two points in Euclidean geometry, the theorem is crucial. Anyone who took geometry in high school, in my opinion, cannot possibly fail to remember it long after other math concepts have been completely forgotten because it is so fundamental and well-known.

Using Pythagorean theorem

The hypotenuse is the Distance from pylon B to pylon C

c = [tex]\sqrt{a^2 + b^2}[/tex]

Distance from pylon B to pylon C =  [tex]\sqrt{845^2 + 567^2}[/tex]

                                                        = 1017.60 m

Factorization in mathematics is the method of dividing a large number into tiny ones that, when multiplied together, give you the original number. Factorization is the split of a number into its factors or divisors.

We can also format it as

9x²−3x−20=9x²−15x+12x−20

  28 +8√5 ≈ 45.89 cm

Step-by-step explanation:

You want the perimeter of an isosceles trapezoid with bases 10 and 18 cm and height 8 cm.

The length of each side of the trapezoid is the hypotenuse of a right triangle with legs 4 and 8:

  c² = a² +b²

  c² = 4² +8² = 16 +64 = 80

  c = √80 = 4√5 . . . . . . length of one side of the trapezoid

The perimeter is the sum of the lengths of the sides and the bases:

  10 + 18 + 2(4√5) = 28 +8√5 . . . . . cm

The perimeter is 28 +8√5 ≈ 45.89 cm.

The length of the arc on a circle of radius r intercepted by a central angle θ is about 67.02 inches.

What is length of arc?

The distance between two places in a curve's section is known as the arc length. Any portion of a circle's circumference is an arc. An arc's angle at any given location is the angle created by the two line segments connecting that point to the arc's endpoints.

A circle has circumference 2πr.

240° is 240/360 of a circle or

24/36 = 6/9

= 2/3 of the circle

The arc is 2/3 of 2πr

= 2/3 x 2pi x 16 inches

General formula for the length of an arc is -

Arc Length = θ × r, with θ in radians 240 degrees

= 4π/3 radians

Arc = 4pi/3 x 16

= 64pi/3

= about 67.02 inches
